I have Canon 7D and speedlite flash 550EX . Does this ST-E3-RT compatilbe with my Flash?

Nope. It only works with the canon 600 speedlite series. Although the 600 series can fire the 500 through its infrared sensor. Hope this helped you.

I don't think so, it's a radio trigger only, your flash is an infrared rcvr only. You can use the ST-E2 transmitter, which is an IR transmitter

It has a non radio setting or put differently an option to use infrared over radio. If you go to Canon's site you might find more info there regarding compatability with other flashes.

Yes, I have the 550D (T2i,Kiss X4) and it works great; a simple & reliable flash that does the job.

If the Rebel Xsi supports ETTL mode for regular Canon Speedlites, then this flash will work also. Otherwise, you can always go to manual (M) mode and use a flash meter to set the correct exposure.

The Canon Speedlight 600 EX Flash is excelente, I used it with my Canon 7D.

Yes, I have a both a 5D Mk3 and a 7D, and this model works fine on both. It's a Canon-standard shutter release cord that comes with this remote, it should work just fine on any Canon DSLR, but I can specifically confirm it for both of these models.

I was unable to get the provided cord to work with my 430EX and Canon 5D mkII. The flash would fire, but no TTL functions. The camera did not recognize the flash when it was on the cord. I ended up going with a "Vello TTL-Off-Camera Flash Cord" and bought the bracket separately for roughly the same price.

I do not know if it works with that kind of flash, I am using 2 flashes: Yongnuo YN 560 for Canon Nikon Pentax III and YongNuo YN-468 II E-TTL Speedlite With LCD Display, for Canon 50D 40D T1i Xsi XS, and works perfectly. And my camera is canon t3i

Yes it is compatible with all Canon EF and EF-S mount cameras... I own a EF 70-200 f4 L and use it on my Canon Rebel XSi (450D) and my 60D. Both of which use the EF-S mount used on your 550D.

agree with other posts, it "should" work with any modern Canon camera flash pair. It should have all the same functions that your flash has with the camera now. (for example - if you have a 3rd party flash that doesn't do something like E-TTL now it won't work with this either). Works well with 60D and 430EX II speed-light combo.

Probably you can't. The way I trigger my Canon flash and my studio strobes simultaneously, with the ST-E3-RT is the following: I set the studio strobes to optical trigger, and then I use the transmitter to trigger my Canon flash. When the studio strobes "see" the Canon flash they also flash. It works, but the color temperature between the Canon and the stuio lights is never the same, and the recycling time for the Canon flash is much slower than the studio strobes, so it's not perfect :)

It fit with my Canon 5d Mark III and 7d canon. I think it's universal size of mount on your flash.

I cannot answer specifically about TTL compatibility back to the T3i, but since it is compatible with the 30D, I would expect it would also work with your T3i. It will surely work in manual mode in any Canon with a hot shoe and any dSLR with a large central contact in a hot shoe.

I am not sure, mine is Canon 60D I am struggling to sync this flash with my camera

see photos I've posted. Should work with just about any available speedlight. Nothing brand- or model-specific about it. Wrap the velcro around the head of the flash gun with velcro part facing OUT, then 'stick' the softbox onto the velcro - works great.

No. You need canon 600 rt or equivalent. This system is radio controlled and your flashes do not have that capability.

Yes it will. I first used this on my CANON XT & then on my 50D right into my 5Dmk3. I now use it as a slave flash with no problems at all.

I have a canon t3i/600D and it works fine. It is a very bright/strong flash.
